Both my surgeon and physical therapist told me 8 weeks but I cheated and got in bed at 6 weeks 🤗

I think you should consider using the whole six weeks to ensure that muscles and joints are ready to switch to the bed. As I said, I was quite uncomfortable during the night and in the AM when using the bed. Maybe it has something to do with the anatomy of the shoulder and how lying flat as opposed to reclining affects it. I'll be trying the bed again in a few days (it did feel great to lie flat in bed on my first attempt). Pain is greatly diminished from first postoperative days but I'm still taking pain meds. I think I'm too active and don't think before I 'make a move'. No changing that at 81 years -

My surgeon and PT guy said to sleep where I feel most comfortable. I tried the recliner, but it was too upright and felt crowded to me. I am used to a very flat pillow. For night use I preferred the bed and used it after the first night. I did have a bed wedge for my back and extra pillows I could arrange for arm support. That was still more upright than I am used to, but more tolerable than the confinement of the recliner.
